  • Patent number: 9332377
    Abstract: The present invention concerns devices and methods for control of data transfer in a personal area network. The data transfer being performed by body coupled communication (BCC) and short-range wireless communication between a first portable electronic communication device (10) and a second portable electronic communication device (20, 30). The devices being adapted to be in close proximity to a body of a user and the first portable electronic communication device (10) is configured to initiate and perform execution of predefined actions by means of the method to cooperate with the second portable electronic communication device (20, 30) in a system/personal area network.

  • Patent number: 8806021
    Abstract: Methods, portable electronic devices, systems and computer program products are provided for automatically creating a social networking service (SNS) session. The methods include generating at and transmitting from a first device a first audio and/or video fingerprint of an audio and/or video event. The first audio and/or video fingerprint has a first predetermined length (T). A second audio and/or video fingerprint is periodically transmitted to a server from the first device. The second audio and/or video fingerprint has a second predetermined length (t), smaller than the first predetermined length (T), and includes data associated with the audio and/or video event that is later in time than data included in the first audio and/or video fingerprint.

  • Publication number: 20140219581
    Abstract: An object of the present invention is to provide a way of improving the stitching procedure. The object is achieved by a method in an electronic device for creating a combined image. The method comprises obtaining (701) a first set of at least two sub-images recorded by an array camera. The method further comprises obtaining (702) a second set of at least two sub-images recorded by the array camera. A first depth map is calculated for the first set of sub-images. The first depth map comprises information about a first plane of the sub-images and a second plane of the sub-images. The first plane being at a first distance from the point where the sub-images have been recorded, and the second plane being at a second distance from the point where the sub-images have been recorded. A second depth map is calculated for the second set of sub-images. The second depth map comprises information about the first plane and the second plane.

  • Publication number: 20130141433
    Abstract: Methods for obtaining a three-dimensional (3D) mesh from two dimensional images are provided. The methods include obtaining a series of 2D images using a camera array; calculating a depth map using the obtained series of 2D images; identifying portions of the calculated depth map that need additional detail; applying a textured based algorithm to the identified portions of the calculated depth map to obtain the additional detail in the depth map; and combining the calculated depth map with the obtained additional detail to provide a more accurate 3D mesh. Related systems and computer program products are also provided.

  • Publication number: 20090054058
    Abstract: A system and method for a plurality of electronic equipment located within a short range communication zone to share bandwidth with each other. In one aspect of the invention, an electronic equipment (a requesting electronic equipment) transmits a request for content over a cellular telephone network (e.g., 3G, GPRS, etc.). In addition, the electronic equipment communicates with other electronic equipment through a wireless local area network (WLAN) interface (e.g., Bluetooth, 802.11, etc.) to determine if the other electronic equipment are available to share bandwidth with the requesting electronic equipment. The other electronic transmit the requested content to the master portable communication device through the WLAN interface.

  • Publication number: 20080293448
    Abstract: According to the invention a first communication device investigates if there is an entry of a contacting identifier received in the device in a contacts register. In case there is no such entry it locates, in the contacts register, communication devices in a set of communication devices providing a lookup service, which set includes at least one communication device and where at least one communication device is a personal communication device, an sends a query regarding the contacting identifier to at least one second communication device of the set. The second communication device receives the query and investigates an own contacts register. In case the contacting identifier is provided in the own contacts register it further locates an identity associated with the contacting identifier and automatically sends data regarding the identity to the first communication device as a response to the query.

  • Publication number: 20080209213
    Abstract: A system receives a request to access a secure resource and a verification telephone number from a first device, establishes a secure session with a second device associated with the verification telephone number, requests an authentication mechanism from the second device to verify the secure resource request, verifies the received authentication mechanism if the requested authentication mechanism is received from the second device, and determines whether to grant or deny the first device access to the secure resource based on the verification of the received authentication mechanism.

  • Publication number: 20020094133
    Abstract: A device and a method for recording of text by imaging the text on a light-sensitive sensor (8). The device converts the images (14-17, 47-49) into a set of characters (50, 51) each using character recognition, and then assembling the acts of characters (50, 51) with the aid of the characters.
